FIG 1. A–C, Quantitative and qualitative analysis among the six sequences for CNR (A), lesion detection (B), and conspicuity of internal architecture (C). GRE indicates gradient-echo sequence; GRE-EPI, GRE-type echo-planar imaging; SE-EPI, spin-echo–type echo-planar imaging; TSE, turbo spin-echo sequence; HASTE, half-Fourier acquisition single-shot turbo spin-echo sequence; s-HASTE, segmented-HASTE sequence
